The Sturmey Archer S2 Duomatic hub is the heart of this wheel! One of their most anticipated hubs ever, this wheel gives fixie and singlespeed riders the chance to still preserve the clean look of their bikes, while adding 1 more gear!

This wheel features a simple, cheap and effective 2-ratio gear that'll be a favourite for singlespeed riders looking for gearing options.

(Please note: You are getting the REAR Wheel only!)

Why YOU Will Love This Wheel:

Available in 5 HOT Colours to match your bike!

Doesn't require any kind of cabling

Just kick back on the pedals to shift between the two ratios, direct drive (not fixed) and an overdrive of 138%

Takes a standard Sturmey Archer 3-spline sprocket and is held in place with track nuts and non-turn washers

Lighter than most hub gears, but is sturdy and tightly built

"makes a lot of sense for anyone that likes the clean lines of a singlespeed but secretly wishes the hills weren't so hard. And it's cheaper than many standard track hubs."-road.cc (4/5 stars)

"You get to keep the clean lines and low-maintenance chain setup and you gain an extra gear. Everyone's a winner"-JM (online review 5/5 stars)

More Reasons to Love This Hub/Wheel:

No shifter cable or associated wear issues

Excellent gear option for urban cycling

Great for those who have a single speed but in some instances need to climb steeper hills

Hassle-free, just a quick back-pedal and voilá... the shift is made

Ideal for bikes that have narrow handlebars which are great to run between cars in trafic jams and when the hill starts you just shift

Ideal for flat urban cycling

(Please note: You are getting the REAR Wheel only!)

Long term use, 4 1/2 years at 60-80km per week urban

by Terry

My Sturmey Archer S2 wheel still runs great after 4 1/2 years. Replaced the 18 tooth with a 20 tooth sprocket. Stripped and rebuilt it twice and have replaced the cage bearings with SKF #20 loose balls with Shimano Dura ace grease and feels great. The sequential change is a minor rock back of the pedals, it will phantom change as the bike rocks over bumps or kerbs but just keep pedaling to stop this. Some auto shifts are to my benefit! It is a great gear hub to use in the traffic as you don't need to take your eyes off the road in front as the change is carried out by a short back rock of the pedals. I was looking at getting a spare S2 Duomatic wheel, in case at $99, but they are sold out.

Great wheel. Slow post

by Jrb005

Love the wheel. I have a hilly commute and this wheel is the business. A perfect solution for me. Very happy with wheel. Be warned of slow post. It took 2 weeks from Sydney to brisbane. Probably not Cells fault ... just saying.

Sturmey Archer S2 Duomatic Hub 700C Wheel

by sven - verified purchaser

I purchased the Duomatic Hub built into a deep v rim to fit on my Cell Mallet fixie.�Arrived on time & easily bolted on. Only extra I had to buy from my local shop was a valve extension for that super deep v rim.�I now have a great 2 speed bike that can handle the hills. I have a lower gear & a higher gear than when it was a single speed. Well worth the money to increase my Cell Mallets use. Thank You Cell Bikes,�Regards,�Sven.

Sturmey Archer S2 Duomatic Hub

by Matt - verified purchaser

This is a great product for those that feel a single gear is not enough.��The included 18 tooth is fine in the low gear but a bit much for the Hi gear unless you are a grinder. With a 20 tooth sprocket you get easy climbing and a good turn of speed in the higher gear on the flats - the best of both worlds.��Shifting is a an art that takes a bit of finesse but the free wheel volume is the simple indicator of which gear you are in - Quiet tick low - Loud Hi.��The wheel seems to be strong, well built and runs very true.��Overall highly recommended for its function and it also has a cool factor.

Path Racer

by Greg - verified purchaser

I bought one of these to convert one of my fixies from fixie to "path racer"��Some moustache handlebars, 32mm slicks and the Doumatic Hub, have combined to make my favourite custom build to date. ��Running a 44t chainring on the front, the two gear options are perfect!! ��Dispatched and in my hands in no time, thanks Cell.

Sturmey S2

by dingr - verified purchaser

Hi there, bought this wheel for a working bike, and after a false start ( first one was pretzeled on delivery, which the guys sorted real fast ) have been very impressed. It is a true 2 speed and although not a perfect science on changes between gears, it has been very usable. I reserve judgment on how strong and long lasting the hub is, as its been not long enough to tell, however, it is pretty smooth and seems pretty robust. Do get a wheel trueing after a bit as one would with any new factory wheel. Get back to you when I destroy something on Sydneys goat tracks... I mean roads.

Superb & essential for any city bike

by Nate

Exceptional & must have wheel for any single speed setup.�I used to run a 53-17 on my 11km commute to/from work, great for a mid-high range speed - but terrible for starting up hills.�With a 49t on front - I now have the equivalent of 44-16 & 60-16 in exactly the same package - no cable routing, no hassles - just bolt in the new wheel.�You'll need 60mm valves on your tubes for the wheel as noted before.��I've been using the wheel for 2 weeks now and it has been superb!�I'm finding that it changes PERFECTLY every time - as long as I do the same thing each time!�1/4 rotation on the pedals works well, you just need to find how YOU can consistently change gears.�You dont need to kick back quickly or slowly, just smoothly to the same point each time & it'll perform fine.�The wheel its made with is fine - hit a few potholes, got a pinch flat & the wheel is fine.��The wheel is also built very well, I didnt look at the bearing pre-loads or the lubricating situation, but bolted it in & it spins for ages & very freely.��I'm about to start with a 20km commute with lots of hills - so I purchased it just in time & very confident it'll do me well.��Cycle to work, get a cheap single speed & throw this on it. ZERO maintenance commuting.

Get product

by Tom D - verified purchaser

Communiting around Canberra. Good to have the versatility of an extra gear. IMHO the 18 teeth 1 to 1 ratio may be a little high on the hills(I run a 46t chainring).

Does the job well

by Mike - verified purchaser

I ride with friends who have gears and I could not keep up down hill. The overdrive feature means I can now keep up down hills and on long flat sections better. The simple mechanism means it still has all the advantages of a single speed.

2 Gears on my old singlespeed

by JJJake - verified purchaser

I bought this for my singlespeed, to help get me up a steep hill. When the wheel/hub first arrived I thought it was quite heavy. Once I put it on the bike the extra weight hasn't made much difference but the extra gear has helped.��I was after a low gear for the hill. The gear ratio the hub comes with wasn't low/easy enough... so I had to change the front chain ring(to a smaller one) as well.�Now I have a two speed bike.. which can get me up that beast of a hill.�It's still requires effort but is a lot easier than doing it on a single speed.

Add some pursuit fun to your SS

by Pomgolian

I have had this wheel for 2 weeks now and have done over 400km on it.�The back kick to change gear is very subtle, only about 1/8th of a pedal stroke. If you kick back ¼ of a stroke it changes back to the original ratio again. So it effectively changes up and down continuously as you pedal backwards.�The gear changes are not 100% consistent. It does occasionally not change, or changes twice, back to the same gear. At a guess, I would say 80 – 90% of the time it changes as you expect. However, some of this could be technique, but after 400km, I doubt it will improve. If you have the bike on a stand and rotate the cranks with your hands however, it seems to change very consistently. �The hit or miss rate on the change is not really an issue, just flick the cranks again and it changes.�You can hear which gear you are in when coasting to a stop, the secondary paws on the planetary gears have a different note than the primary paws for first gear.�This wheel is not a replacement for a derailleur based gear system, nor is it a replacement for a cable shift internal hub system. Where this hub excels is for those who like to ride a single speed, are not concerned about having a lower gear for climbing, but want a taller gear for chasing someone down when you are out for a bit of fun.�I have been commuting on a single speed Surly Steamroller for over 6 years and had worn the braking surfaces and bearings out on my original wheels. I rebuilt the front wheel and, for the same price as a new rim and bearings, thought I would give one of these wheels a try. I would describe the build quality as robust, and certainly great value for money.�It brought a new level of enjoyment to my daily ride. It still rides like a single speed, but you can kick it into second gear and really mash the pedals for a bit of urban pursuit. The change is a little tall, I run a 48-18 combination for the 1:1 first gear, but in second, with 138% overdrive, it is effectively a 48-13 which is 99 gear inches. Great if you are a gorilla. A 48-19 would probably be a better ratio for humans, but the wheel shipped with an 18 which was my original rear sprocket size anyway.

Second nature with practice

by Terry

The Sturmey Archer S2 is a unique hub system. It took some time to fully master the shifting mechanism but now after learning the back pedal or 'kick' is very light and only a few centimetres or inches on the pedal. Any reverse movement will change the gear even when freewheeling and hitting a bump. A gentle light small movement backwards changes or toggles the gears. It is a pleasure to ride and the standard ratios are great for my urban use. The gear change is second nature now. I have the S2 fitted to a Cell Stinger with matching Gold rims which attracts considerable interest. Looks quality and expensive?

Why are you still riding single speed?

by ThirtyFerretsInAManSuit - verified purchaser

First, you'll want to use tubes with valves as long as possible (more than 50mm) because the rim is quite deep. I might have preferred a different rim with the same hub.��Second, do a calculation and work out what size chainring you should use it with. This comes with an 18tooth sprocket, and its higher ratio is the same as a single speed hub with a 13t sprocket. Think 13t for cruising, 18t for accelerating.��After about 2 weeks of using this, I'm happy with it; it's exactly what I expected from the description. The package is around the same price as a single speed rear wheel, but it simply has more function, so if you're building on a single speed frame you might as well use this wheel and make it dual speed.��The two ratios are different enough that you can always tell which one you're using from the feel. It doesn't always stay on one gear when I let it freewheel, especially when moving fast. And it can take a few tries to change gears. So sometimes it will waste a few precious seconds, which is a small price to pay. I'm sure I'll get better at using it.��I can't comment on its durability yet.

a great compromise

by Patpug - verified purchaser

I put this on my fixed gear 2009 Bowery after moving to a very hilly area,Its good to have a second gear,the gear change is easy once you get used to it and the freewheel makes a little noise but after riding a fixed gear for 6 years maybe its just me.Its laced to a deep v rim which seems to be good quality as well.Its good to see Sturmley Archer making these hubs again
